lmlorc rvlorroil to, Whii'h provided with an tubing, before mentioned.

tubing, shown in Fig. 7, as connecting the intake nipple a, to, which isattached the adjacent end of a tube or metal pipe conveying compressedair from the airpump, which is partof the usual air-brake mechanism,while an outlet pipe a receives the adjacent end of the flexible tubingcommunicating with the eye-pieces of the goggle frame and conveys theair from said tank to said goggle frame, only portions of which tubingor pipe are shown in the drawing.

In Fig. 7 is shown,,a piece of metal tubing (1, supplied with a globevalve A to regulate the llow of air from the tank to the eyepicces,said. metal tubing having its ends secured. in the adjacent, ends of theflexible nipples of the metal pipe (1 with the air tank, may be omittedand the metal pipe may be continued direct from the air tank to thedesired point, so as to bring the globe valve A to a point within easyreach of the opcrat or, but any other suitable valve may be used inplace of the globe valve, here mentioned.

An air accumulator, which is preferably in the form of a funnel, may beapplied to the front part of the vehicle, having its open end forwardlyand its converging sides rearwardlv disposed, forming; the apex of ahorizontal cone, which apex is secured my 'the forward end a of thethird branch, so as to have interior connection thcrcthrough with thefork A conducting the air accumulated by .raid funnel intothe flexibletubing; of the eye-pieces. The construction of this funnel and itstubular connection being so well known that the separate illustrationthereof is deemed superfluous.

it will here be remarked that I. do not limit myself to the preciseconstruction hcreinbcfore described, for minor alteratrons may be madewithout departmg ironr the spirit of the invention,

The invention having thus l'iecn ascerrtained and described, and themanner in which its functions are performed fully shown and. set forthwhat is considered new The fleXibl e plate l'ormet and desired to besecured by Letters Patent 1s:

1. in a device of the class described, consisting of an eye protector, aframe formed of two adjacent tubular circular eye frames formed withopenings in their periphery, a tubular nosebridge connecting" said eyeframes, means for connecting said eye frames to flexible pi ing, andmeansfor supporting said flexil) e tubes and securing the device to thehead of the wearer, for the purpose set forth.

2. in a device of the class described, consisting of an eye protectingframe formed of tubular circular eye frames; openings formed in the)6ll)l1( 1, of said eye frame, a tubular nose-l ri fge the ends of whichare secured to the adjacent sides of said eye frames, nipples secured tosaid eye frames, flexible tubes having their forwardends secured to saidnipples and their rear ends secured to a if-shaped connectin pipe, meansfor circulating air through said tubes and nipples, and means forliberating said air from the openings in the periphery of said frames.

3. in a device of the class described, an eye protecting frame, formedof two tubular eye frames, openings through the walls of theirperiphery, a tubular nose-bridge connecting said eye frz'nnes atadjacent points up'van their periphery, nipples secured to said eyeframes at their extreme opposite outer cdg0s,lleXiblc tubes having theirforward ends secured to said nipples, a Yshaped tubular connectionconnecting the rear ends of said flexible tubes with each other and to asource of air supply, a curved slide 1 with clam ings embracing saidflexible tubes and slidab y ad irstable thereon.

in testimony whereof I ahix my signature, in presence of two subscribingwitnesses.
